I can't think of a single good reason to lock up all tabs in the user's browser.
In your example: Show a modal popup for the user to log in. Once submitted, disable the Submit button. If the login fails, show a message and enable the Submit button. If the login succeeds, remove the modal popup. Why lock up all the tabs in the browser? It's an unnecessarily unfriendly thing to do.
